SPECIFICATION forming part'of Letters Patent No. 624,642, dated May 9, 1899.

Application filed March 26, 1898. Serial No. 675,274. (No model.)

1 '0 ct whom, it may concern:

Be it known thatI, FELIX G. GARDNER,a citizen of the United States,residing at Oeleste,in

the county of Hunt and State of Texas, have simple and improved pump mechanism or apparatus of this class which will possess advantages in point of .positive operation, inexpensiveness in construction, effectiveness, power, adaptability to various uses, convenience, and general efficiency.

In the drawings, Figure 1 is a top or plan view of my improved pump mechanism. Fig. 2 is a plan view of the piston. Fig. 3 is a side or edge view of the apparatus. Fig. 4: is a detail transverse sectional viewtaken on the line y y, Fig. 2. Fig 5 is a plan view of the base-piece. Fig. 6 is a plan view of the middle piece. Fig. 7 is a transverse sectional view taken through the base-piece and its rim. Fig. 8 is a detail sectional view taken on the line a 2, Fig. 5. Fig. 9 is a transverse sectional view taken through the middle piece. Fig. 10 is adetail transverse sectional view taken on the line to to, Fig. 6. Fig. 11 is a transverse sectional view taken through the top piece. Fig. 12 is a detail transverse sectional view taken on the line :3 m, Fig. 1. Fig. 4 is a detail perspective view of one of the valves.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the base-piece or bottom, which is provided with an annular rim CL and with a segmental groove or channel a in its top surface, having inclined or beveled ends a a the purpose of which groove or channel is to accommodate the valve when the whole is turned downwardly in the operation of the mechanism.

The inclined or beveled ends a serve as guides for the valve in its rising movement.

B designates a revolving piston, which fits within-the rim of the bottom or base-piece and carries hinged valves 0, arranged in a circular series. These valves are of rightangular construction, embodying a base arm or foot 0, which is adapted to be received by a corresponding recess b in the under side of the piston when the valve is up in an open position (illustrated in Fig. 4) and said foot is traveling upon the top surface of the base A. At right angles to the foot 0 the valve comprises a head 0, which is adapted to rest upon a seat I) in the piston when the valve is closed. The valve is hinged, as at 0 at the vertex of the angle formed by its two arms'or portions, as shown in Fig. 4.

D designates a middle piece which is mounted abovethe piston and is providedwith a segmental slot d, which forms-almost a complete circle and is adapted to accommodate the head cof the valves. Communicating with one end of'the slot or passage 01 is an inlet 6, through which the water is fed to the pump. At the opposite end of the slot (1 its diameter is contracted, as at d d, to provide inclined or beveled ways 01 at the under side of said contracted portion, which operates to carry the head 0 of thevalves downwardly and close them upon their seat I). It will be understood that when the valves are thus closed their foot 0 is received by the groove 0. in the base A, and the head 0" of the closed valve travels under the middle piece D until it reaches the initial end of the slot d at the inlet 9, when the valve again rises in the slot d by means of the contact of its foot 0 with the beveled ends a of the groove 0., so that its head, 0 rises back of the water-supply and forces the same through the slot (1.

piece or bottom A, as shown at g, in themiddle piece D, as shown at c, and in the cappiece or top F, as shown at 9 An operating-crank H may be attached to the outer end of the shaft G, or said shaft may be provided with any other suitable de vice by which it may be operated by hand or power, as desired.

The cap-piece-F may be provided with segmental slots or openings f f, covered and closed by transparent plates i, of glass or other suitable material, through which the interior of the pump mechanism may be inspected.

The bottom or base-piece, piston, middle piece or member, and top or cap-piece are all preferably of flat circular or disk shape, having the relatively-arranged segmental slots or grooves, as above described, and assembled togetherin parallel superposed positions, as shown, whereby the whole forms a simple and compact pump device which will operate with great power and effectiveness tion will be readily understood. The water enters at the inlet 6 into the segmental groove 1 or passage 01 of the middle piece, and as the piston is turned or revolved by means of its shaft the hinged valves rise at the initial end of the slot (1 and force the water through the same and the outletfat the terminal end of the slot, when the hinged valves close and' pass under the middle piece D until they again reach the initial end of the slot d. The

rotary operation of the piston and its hinged valves is adapted to force the water with great power, so that it will throw a stream for a.

sage above said groove or channel, water inlet and outlet connections at the respective ends of said'passage, and a rotary piston arranged between said groove or channel and said passage and carrying angular valves operating upon a fulcrum and embodying divergentl y-proj ectin g arms adapted to project respectively into said groove or channel and said passage when the valve turns upon its fulcrum, substantially as and for the purpose set forth. a

2. An improved pump of the class described, comprising a closed casing embodying a base having a segmental groove or channel in its top surface, a middle piece having a relatively-arranged segmental slot or passage provided with Water inlet and outlet connections at its respective ends, and a cappiece or cover, in combination with a disk forming a rotary piston inclosed within said casing be tween the base and middle piece and carry ing angular hinged valves embodying arms adapted to project at its opposite sides and in relation to said channel and said passage, substantially as and for the purpose setforth. 3. An improved pump of the class described, comprising a closed casing embodying in superposed relation a base having in its top surface a segmental groove or channel with guide-inclines at its ends, a middle piece having a relatively-arranged segmental slot or passage provided with water inlet and outlet connections at its respective ends and with a guide-incline at its terminal end extending with relation to said channel, and a cap-piece or cover, in combination with a rotary disk forming a piston and carried upon a shaft transversely mounted in said casing, said piston having mounted in itright-angular hinged valves the arms of which are adapted to project at opposite sidesand operate in said channel and said passage, substantially as and for the purpose set forth.

' In testimony whereof I affix my signature in presence of two witnesses.
